Kawasaki ZX-10R 3/4 Race Series system
Yoshimura's new AT2 3/4 system for the 2021 Kawasaki ZX-10R and RR sport bikes has been retuned for the electronics and emissions updates Kawasaki made to the revised ZX-10 engine for 2021.
"The stock header on the ZX-10R is hard to beat," says Yoshimura R&D of America's 'Big E' Erick Bartoldus. "Made of titanium, it performs very well for a stock unit, so our engineers focused on where they could make the most gains. Rather than an entire system, it seemed perfect to develop a 3/4 Race Series system.
"Our AT2 styling and performance is perfect for Kawasaki's newest litre bike. Dripping with looks and performance, the AT2 woke up the 998 cc inline four cylinder engine like you would expect, enhancing the maximum hp by a huge 10.4% and torque by an additional 7.7% throughout the entire rev range.
"Substantial weight savings were achieved as well. The AT2 3/4 system drops over 8 lbs (3.63 kg) over the stock muffler while providing that insane Yoshimura AT2 exhaust note."
